A man detonated a small bomb in Beijing's airport, injuring only himself. Whats interesting about this story is that he was shouting about having an explosive but was completely ignored by everyone else in the airport. It was only when he pulled the bomb out that anyone paid attention to the attacker. This is completely different from US Airports. Even speaking about any kind of threat to the public safety will result in TSA questioning. Anyone claiming to have a bomb would draw immediate attention.
